The effect is as follows: the wax precipitation well section of the oil well is heated discontinuously or continuously through the double hollow sucker rods, so that the temperature of the well head of the oil well is higher than a wax precipitation point, the normal production of the oil well is met under the conditions of no chemicals and no hot washing, and the effective rate of the oil well is improved by 19.84 percent.
Description
Technical field
The utility model relates to oil recovery technique field, oil field, relates in particular to a kind of flow string of high waxy oil well, is a kind of pumping pipe string that is connected with double hollow oil pumping rod, and oil well paraffinication well section is carried out continuously or the interruption heating, removes wax deposition, satisfies the oil well ordinary production.
Background technology
At present, the higher oil well of paraffin content needs regularly in well the dosing viscosity reduction or adopts hot washing method to keep the ordinary production of oil well, production management inconvenience in oil recovery process.Oil well heat is washed and can be polluted oil reservoir; The water discharge time that heat is washed is longer, influences oil well output; Simultaneously, the termination of pumping overlong time, oil pump can not normally rise and take out, rate when influencing the production of oil well, thus influence well yield.
The Chinese patent publication number is: CN201110133, a kind of double hollow oil pumping rod is provided, and comprising: hollow outer bar and the inner concentric with it interior bar of hollow thereof, the female of hollow outer bar is fixedly connected by bar in flange and the hollow, and flange is provided with through hole.Rod outer surface is provided with insulating in hollow, is provided with plum blossom external screw thread nut between the bar in hollow outer bar male and the hollow.Interior bar is covered with the heat-insulation and heat-preservation material outward, makes thermal medium reach best effect of heat insulation.Bar in outer bar male plum blossom external screw thread nut is fixing, outer like this bar cause at the volley and flexiblely make the interior bar also can be synchronous, do not cause the tensile phenomenon of interior bar; Guarantee the smooth and easy circulation of thermal medium.
The utility model content
The purpose of this utility model is: a kind of high waxy oil well pumping pipe string is provided, adopts double hollow oil pumping rod that the paraffin-troubled well section of oil well is carried out continuously or hot water circuit heating discontinuously, remove wax deposition, satisfy the oil well ordinary production.
The technical solution adopted in the utility model is: high waxy oil well pumping pipe string, mainly form by starting taper, gas anchor and screen casing, tail pipe, oil well pump, oil pipe, double hollow oil pumping rod, sucker rod change snapping head and sucker rod.Be fixed with tubing string in sleeve pipe, tubing string is connected with starting taper from bottom to top, and the top of starting taper is connected with gas anchor and screen casing, and the top of gas anchor and screen casing is connected with tail pipe, and the top of tail pipe is connected with oil well pump, and the top of oil well pump is connected with oil pipe; It is characterized in that: be connected with sucker rod in tubing string and on the top of oil well pump, the top of sucker rod is connected with sucker rod and becomes the snapping head, and the top that sucker rod becomes the snapping head is connected with double hollow oil pumping rod, and double hollow oil pumping rod is connected to ground always.
What oil well pump adopted is that diameter of plunger is the plunger oil-well pump of 38mm.It is the solid sucker rod of 22mm that sucker rod adopts diameter.What double hollow oil pumping rod adopted is that external diameter is the double hollow oil pumping rod of 42mm.
There is sale in double hollow oil pumping rod market.Co., Ltd produces double hollow oil pumping rod as the auspicious auspicious petroleum thermal recovery equipment in Hengshui.
The using method of high waxy oil well pumping pipe string, wax precipitation point, wax deposition section according to different paraffin content oil wells, after two hollow stems and solid hopkinson bar made up, determine different running parameters, paraffin content was opened two hollow stem heating system circulation primary in per 10 days less than 20% oil well, and a time is 24 hours.Inject hot water or steam from the interior pipe of double hollow oil pumping rod 7, hot water or steam arrive wax deposition district, down-hole, and thawing was given rise to ground with extraction liquid after wax deposition absorbed heat.Solve the high content of wax or high condensation point or high colloid, the asphalt content oil well is kept the oil well ordinary production in not dosing or the not hot situation of washing.
The beneficial effects of the utility model: high waxy oil well pumping pipe string, realize oil well paraffinication well section is interrupted or heating continuously by double hollow oil pumping rod, can make the well mouth of oil well temperature be higher than wax precipitation point, under not dosing, not hot situation of washing, satisfy the oil well ordinary production, improve efficient 19.84 percentage points of oil well; Reduced the conveying back pressure of gathering line simultaneously.
Description of drawings
